in addition to what LR777 said, i was able to closely inspect the abovementioned new design power operated retractable lid...
a future Baguio BOSB- (his name is March, 2010 GLS Sport M/T user) had this installed at Carryboy La Union to the tune to about P39-40 thousand coins of Jose Rizal!

. it was installed after he purchased the truck on October 2009.
the design looks promising. the rail at both sides has a gutter that also has a drainage on all 4 corners so the concentration of water flow goes through it. March also advised that at one time, during the heavy rains up here in Baguio last month the bed interior was still totally dry- much need on his case since he delivers paper products. the lid itself has a hook that locks the tailgate BUT im not convinced of its capability since the hook from the lid is quite small. perhaps a barrel bolt used in canopies on both sides from the inside will help out further. once the lid is closed, it can handle up to 5 kilos on top of it without damage.
to those who appreciate the current shape of the strada will like this. since the retractable lid is bolted on the bedside. its streamlined design shows minimal visual from the side view will eliminate the bulkiness of the current hard lids like the GSR and GSX of carryboy. the downside of it- even with the old design lid is that the depth of the pickup bed will be compromised due to the rails.
it doesn't totally retract. it left about 15% of it before reaching the motor. so for those who are expecting a real open pickup bed with this lid, you might want to think again.
but nonetheless, this new design is a step in the right direction. perhaps a bit more of fine tuning and this will really sell!
